📚 Quick Study Guide

  • 💾 RAM (Random Access Memory): Think of RAM like a whiteboard where the computer writes things it needs to use right now. It's fast but forgets everything when the power is off.
  • 💿 Hard Drive: This is like a notebook where the computer stores things permanently, even when it's turned off. It's slower than RAM but can hold much more information.
  • Cache Memory: A super-fast, small memory that holds the most frequently used information, making the computer run faster. Think of it as the sticky notes you put on your desk for quick reminders.
  • ✏️ Memory Size: Measured in bytes (B), kilobytes (KB), megabytes (MB), gigabytes (GB), and terabytes (TB). $1 \text{ KB} = 1024 \text{ B}$, $1 \text{ MB} = 1024 \text{ KB}$, $1 \text{ GB} = 1024 \text{ MB}$, $1 \text{ TB} = 1024 \text{ GB}$.
